The present invention relates to gas evaporator devices (1) and methods for operating them. By virtue of the improvements according to the invention, the service life of conventional gas evaporator devices can be significantly improved, such that the maintenance and material outlay and hence the costs of the coating method are reduced. This is achieved by virtue of the fact that a shielding element (5) impermeable at least to passage of the material is provided at least between the mixture of gas and material flowing in the section (4), in which material to be evaporated is guided in a gas flow and is heated by the heating element (2), and the heating element (2).

摘要:
A method and system allows multiple and simultaneous use of a pre-paid calling card. A call management system allows for the completion of multiple calls under one pre-paid calling card account number. Depending on the number of concurrent users, a billing system assigns a portion of the total number of available service units to individualized user accounts. The individualized accounts are debited according to the rate charges for each of the calls and are initially assigned an account balance that allows all concurrent users with the same amount of talk time.
摘要:
A semiconductor chip (1) has a metal coating structure (2) which has on an active upper side (3) of the semiconductor chip (1) at least one lower metal layer (8) with copper or copper alloy, on which a central metal layer (9) with nickel is arranged. The metal coating structure (2) is terminated by an upper metal layer (10) of palladium and/or a precious metal. The central metal layer (9) with nickel and/or nickel phosphide has a rough interface (11) with respect to the plastic package molding compound surrounding the metal coating structure (2).
